MACHINE FOR SHEARING METAL.

SPECIFICATION forming'jpart of'Letters Patent No. 247,566, datedSeptember 27, 1881,

u I Application filed June 1, 1881. (No model.) V

To all whom it may concern Be it known that I, NIooLAUs KAEMPF, ofBonduel, in the-county of Shawano and State of Wisconsin, have inventedcertain new and useful Improvementsin Machines for Shearing Metal, and Ido hereby declare that thefollowing is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it'appertains to make and use My invention relates to ametalrout-ting ma chine; and the novelty consists in the construe: tionand arrangement of parts, as will be more fullyhereinafter set forth,andspecificall y pointed out in the claim.

The object of the invention is to provide a machine compact in form,simple in construction, and efficient in service, having sucharrangementand combinations of parts as will afford a maximum of cutting-power in aminimum of space; and to these ends the cuttingpower is transmittedthrough a series of-fulcrumed levers, each of which serves to multiplythe force, as will be explained. v

In the accompanying drawings, which form a part ofthis specification, and which fully illustrate my invention, Figure 1 is a side elevation;Fig. 2, a top-plan view; Fig. 3, a transverse section through thelines wa; in Fig. 2, and Fig. 4 a similar section throughthe lines y y inFig.1.

Referring to the drawings, A represents a body, supported on legs a, andhaving a longitudinal slot orre'cess,'a. Firmly secured to this body isa base-casting of metal, B, the se curing means being seen at I).

Upon the upper surface ofv the casting B are secured journal-frames Bwhich furnish bearings for a shaft, 0, upon which is hung the knifeleverG,carryin g knife 0.

To the-free end of the knife-lever (J is lgosely I link is similarlypivoted at its other extremity to a lever, G fulcrumed at c in the bodyA.

The lever G operatesl ooselyinlmlongitQL nal recess a, and serves toraise or lower the knife at will, and when in the act of cutting thelever system shown greatly multiplies the power.

-D represents the stationary knife fra1ne,upon which is removablysecured the knife d, having a slightly-beveled upper surface. Bothknives c and d are removable, and have about the same form upon theircutting-surfaces.

A curved arm, E, extends upward from the base B, and is adjustablysecured thereto. It bears against the lever O, and by its trans- 6overse adjustment allows the knives to be held 'closel y together at alltimes.

It some instances it is necessary to cut several hundred piecesof thesame length, and in others varying lengths are desired. I have soughttoenable my device to accomplish this work by a peculiar and convenientfeature. pivot at f a measuring-rod, F, upon which is hung anadjusting-block, Gr, adapted to he held in position at any desired pointupon the rod, according to the inch-marks or fractions there of, byaset-screw, g, and it has a ledge, g, upon, which the end of the barbeing operated upon rests. This measuring-arm is readily put out of'theway when not in use by depressing the spring H, having the slot h, inwhich the arm rests, and turning the arm to one side, as isobvious.

The operation of the device is apparent.

What I claim, and desire to secure byLetters Patent, isv Thecombination, With the body A, cutting devices 0 D, and operatingmechanism, of the measuring-arm F, having adjustable block G, providedwith ledge g and thumb-screw g, and the holding spring H, having sloth,-as and for the purpose shown and described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

NIOOLAUS KAEMPF.
